owers,

Specification of Letters Patent.

Original application filed March 1, 1912, Serial No. 680,952. Dividedand this application filed September3,

To all whom it may concern:

Be it known that I, GnoRcn TROMPETER, citizen of the United States,residing at Clearwater, in the county of Sedgwick and State of Kansas,have invented certain new and useful Improvements in Land-Rollers, ofwhich the following is a specification.

This invention relates to improvements in rollers for treating thesurface of the ground preparatory to planting therein and has for itsobject the provision of a roller by which the soil turned up by groundtreating implement traveling in advance of the roller will be thoroughlypacked so that seed planted therein will be held against loss under theinfluence of strong winds or other causes, this application being adivision of an application filed by me March 1, 1912, Serial No.680,952.

The present invention is illustrated in the accompanying drawings andwill be hereinafter first fully described and then more particularlypointed out in the appended claims.

In the drawing, Figure 1 is a side elevation of an apparatus showing myimproved roller in position thereon. Fig. 2 is a detailed plan view,partly broken away of the roller. 7

My improved roller is preferably employed upon an agricultural implementembodying a main frame composed of side bars and cross bars 2 connectingthe same, a central longitudinal beam or perch 3 secured upon the crossbars and projecting slightly beyond same at its ends and braces lconnecting the said perch with the side bars. The steering wheels 5 arecarried by crank axle 6 which is secured to the under side of a tongue 7at the rear end thereof, said tongue 7 being flexibly connected with thefront end of the perch 3 by a universal coupling indicated at 8 and thedraft applying device 9 being secured upon the perch at the front endthereof.

Depending from the side bars 1 of the main frame, at or near the rearends thereof,

- are short standards 20 having journal boxes 21 at their lower ends toreceive the ends of an axle 22 carrying a roller or packer consisting ofa series of disks 23 and 24, the disks 24: being considerably less indiameter than the disks 23 and alternating therewith. The disks are alltapered or beveled toward their edges or peripheries so that they willSerial No. 718,357.

readily take into the ground and aid in the cutting up of the same,while at the same time they are arranged closely together so that theypresent a continuous surface to the ground and consequently pack thesame, as will be understood. The disks are all wheel-like and secured tothe axle or shaft 22 by radial arms or spokes 25, as will be readilyunderstood. Secured to and depending from the rear cross bar 2 of themain frame are a series of scrapers 26 which extend to the packer andinto the spaces between the larger disks 23 so that any soil which maycling to the surface of the disks in the operation of the machine willbe removed therefrom so that they will remain clean and thereforeefiiciently perform their functions, the inner ends or edges of thescrapers being notched to conform to and fit close against theperipheries of the disks.

Hangers 27 are pivotally secured to the main frame at the front and rearthereof and pulverizers 28 are supported from the front hangers whileharrow teeth 29 are supported from the rear hangers, the roller beingdisposed between the two sets of hangers as clearly shown in Fig. 1. Acontrolling lever 30 rises from a rock shaft journaled in suitablebearings carried by the perch 3, said lever being connected by a link 31with a crank arm 32 rising centrally from a rock shaft at the rear endof the perch. These rock shafts have lost-motion connections with rods33 extending to and connected with the ground treating implements andsprings 34 are coiled around the said rods to hold the said elementsyieldably to their work.

By adjusting the lever, the depth to which the implements may take intothe ground may be adjusted as will be readily understood and theimplements will be permitted to yield to any unusual hard obstruct-ionsin their paths by the springs in the usual manner.

It will be readily noted that the larger disks will cut into the groundand will turn to one side the soil at the edges of the furrows which maybe formed by the said disks and this soil will be crushed by the smalldisks and firmly placed or packed so that a fine, solid bed for sowingwheat or other seed will be provided. The soil will also be packedaround the roots of young plants so that no injury may be suffered bythem and lip-rooting of the plants by strong Winds cannot occur. IHaving thus described my invention, What I claim is 1. The combinationWith a main frame, of

a packing roller mounted thereon and con-e sisting of a series of diskshaving beveled edges, the disks being in contact at their sides and thealternating disks being of dif ferent diameters.

2. The combination With a main frame, of a packing roller mountedthereon and consisting of a series of disks having beveled edges, thealternating disks being of diiierent diameters, and a plurality ofscrapers secured to and depending from the frame and extending betweenthe larger I Copies of this patent may be obtained for five cents each,by addressing the Commissioner of Patents,
